KP Pushbutton

SamplingInstallationReliabilityDimensionsSpecsOrder

Overview

  • For use on Engines, Hydraulics, Transmissions, Turbines, Compressors

  • Sample while the equipment is running (up to 750psi)

  • Take hot, circulating, live oil samples directly from pressurized ports to give more representative samples.

  • Reduce the time needed to take samples

  • Avoid opening system and exposing to external contamination

  • Less than 1ml (0.04 fl oz) of deadzone volume to purge

  • Avoid the cost of sample retakes and faulty trend data

  • Avoid the cost of replacement probes or cross contaminated samples

  • Avoid the  and inaccuracy of drain sampling and vacuum pump sampling.

Sampling

  • Sample without shutting down.

  • Sample directly into a bottle, no probes necessary.

  • Push to open, release to close. Fast dynamic sampling.

  • 360 Degree rotatable spout to avoid orientation problems when sampling

  • Omni-directional. Barb on spout can fit a 3/16" PVC tube (1/8" ID) to access difficult locations or reduce foaming with higher pressure/velocity samples.

  • Vacuum sample with suction gun (VAC) and PVC tube (SR). Draw the vacuum- push the button.

  • One hand operation on low pressure systems using the PVC tube (SR) and the vent cap (V)

Installation

  • Install on pressurized ports on engines, compressors & hydraulics upstream of filter and downstream of critical components.

  • Range of thread, materials and seal options to fit directly into most systems. Fewer adapters necessary.

  • Full 360 degree spout rotation to avoid orientation problems. No need for backing off on NPT Pipe threads and compromising seal. 

  • Frame mounted remote access bulkhead with microhose for difficult to locations.

  • Most compact pushbutton available for tight locations.

Reliability

  • Rugged patented valve. Successfully impulse tested to 1,000,000 cycles at 7800psi at Milwaukee School of Engineering Fluid Power Institute.

  • Valve safely limits sampling to approximately 750psi. 6000psi spike resistance on hydraulic lines.

  • Metal cap gives secondary backup sealing (from vacuum to 750psi) and dust protection.

  • Weathersleeve prevents dirt buildup behind button.

  • Brass button and valve design reduces heat transfer
